DESCRIPTION OF THE PREFERRED EMBODIMENT

The following preferred embodiments are just priority ways for this invention. Any other embodiments of same or similar principle and basic structure are all under protection scope of this invention.

Please refer to FIG. 1 to FIG. 6. The invention mainly comprises blade bracket 1 and blade 2, the blade bracket 1 and blade 2 are joined together by the inserting structure. Below is detailed display for this invention by introducing several preferred embodiments.

Embodiment 1

Please refer to FIG. 1 to FIG. 4. The structures in FIG. 1 to FIG. 4 are for this embodiment. Any other embodiments in this specification introduced later that have similar structures as embodiment one are not displayed by attached figures. In this embodiment, there are three mounting holes 3 on the blade 2 and three elastic connectors 4 on the blade bracket 1. The elastic connectors 4 could insert into the mounting holes 3 on the blade 2 and fix the blade 2 to the blade bracket 1. In this embodiment, there are three mounting holes 3 and three matched elastic connectors 4. In actual practice, they could be set as two or more according to actual requirement. And the quantity of mounting holes 3 could be equal or more than the quantity of elastic connectors 4. There are mounting holes on the bottom centre of the elastic connectors 4 in this embodiment. And the elastic connectors 4 are installed on the blade bracket 1 by screws 5. In actual practice, elastic connectors 4 could be installed on the blade bracket 1 by inserting or riveting or other ways. There is a joint part 41 on the bottom of the elastic connector 4. In this embodiment, there are three elastic inserters 42 on the elastic joint 41 and there is space between two adjacent elastic inserters 42. In actual practice, the elastic inserters 42 could be set two or more. There are stoppers 421 on the bottom edge of elastic inserters 42. As the elastic inserters 42 insert into the mounting hole 3, the stoppers 421 are wedged on the edge of the mounting hole 3, which keeps blade 2 and blade bracket 1 relatively fixed. In this embodiment, in order to make the elastic inserters 42 insert into the mounting hole 3 easily, the elastic inserters 42 are designed to be wedge-shaped in front. To be specific, the front of the elastic inserters 42 is similar to the shape of a cone with the front smaller and the end bigger, which make them easily wedge into.

Embodiment 2

The structures for this embodiment are similar to embodiment 1. The differences are: The elastic connectors 4 are installed on the blade 2 while the mounting holes 3 are installed on the blade bracket 1. Other structures are as same as what described in embodiment 1.

During assembling of this invention, we first fix the elastic connectors 4 on the blade bracket 1 or blade 2, and then align the mounting holes 3 with the elastic connectors 4 and press downwards forcibly to securely fix the blade 2 and blade bracket 1 together. In this invention, screws are unnecessary for installing the blade 2 on the blade bracket 1. The process of assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling the blade 2, only a press plate 6 of matched holes with elastic connectors 4 is needed to press the elastic connectors 4 and make the elastic inserters 42 retract to the center, which achieves the separation of the blade 2 from the blade bracket 1.

In this invention, the blade and blade bracket are joined together by the inserting structure. Screws are unnecessary for installing the blade on the blade bracket. The process of assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling the blade, only a press plate with matched holes is needed to press the above-mentioned elastic connectors and separate the blade from the blade bracket, which could greatly enhance the ease of use.
